How to raise potted white orchids?

White orchid is a tree of Magnoliaceae and Michelia. It is a natural cross between Magnolia and Michelia. It is an evergreen native plant growing in South China, Southwest China and Southeast Asia. It can grow to a height of 10 meters and 13 meters. White orchids like light, avoid stagnant water, not cold-resistant, but also afraid of high temperature, suitable for slightly acidic soil. Love high dryness, avoid low dampness, waterlogging is easy to rot roots. The sandy soil, which is fertile, well drained and slightly acidic, can also grow on weakly alkaline soil.

How to raise potted white orchids

1. The choice of flowerpot and soil: the family potted white orchid should be cultivated in loose, breathable and humus-rich soil. Usually choose tile basin with good air permeability, purple sand basin (cylinder) or plastic basin with more bottom holes. The soil in the basin had better have a certain amount of granular soil of different sizes to facilitate water seepage and air permeability.

2. The operation method of changing pots: according to the crown size and age of white orchids, the pots and vats of appropriate size should be replaced to facilitate the exuberant growth of plants. During the operation, you should wait for the pot to dry, tilt the pot (jar) slowly (or upside down), hold the basin in one hand, grasp the plant in the other, and pour out the white orchid and move it into the new pot. The new basin (tank) should be padded with a small amount of loose soil in advance, then irrigated thoroughly, and the planting can be stable.

3. Planting location: from March to April every year, the pots and jars with white orchids are removed from the outside and placed in a sunny place. High temperature in summer, should be appropriate to choose a sunshade net or build a simple shade, so that the white orchid can not only shine on the morning sun, but also avoid the strong light in the summer afternoon (so as not to burn branches and leaves due to exposure).

4. Pruning: potted white orchids should choose the appropriate height, cut off the terminal buds and cut some side branches with shears. After the terminal bud is cut off, it is beneficial to how long the lateral branches are, and the longer the buds are, the more they bloom.

5. Fertilization: in the vigorous period of white orchid growth (usually in May, June or July and August of each year), the white orchid should be given flower fertilizer every half a month or so, or a little nitrogen, phosphorus and potassium compound fertilizer should be applied at about 20, 2 to 6 grams at a time. The specific operation is: first use a small shovel to draw several vertical and horizontal ditches of the soil in the basin, then slowly spread the fertilizer into the ditch, then cover it with the topsoil in the basin, and pour some water. Make the fertilizer gradually infiltrate into the root of the plant with each watering. Do not spread the fertilizer directly to the root, so as not to "burn the root" due to the heavy fertilizer effect of the soil around the root. It is better to apply thin fertilizer frequently, cake fertilizer is better, no fertilizer is applied in winter, fertilizer and water are irrigated every 4 days from July to September, once every 6 days from July to September, and once after several times of fertilizer application.

6. Watering: proper watering is the key to the maintenance of white orchids. White orchids should not be overwatered or overwatered. The correct watering method should be to moisten the soil in the basin at one time, but it is not necessary to water the soil in the basin when it is slightly dry. Remember not to water every day, but you can often spray water on the leaves with a small spray can. In summer, water should be irrigated not less than three or four times a month (plus spraying water on the leaves). The easier way to master is to water the white orchid as long as you see its leaves drooping. It is watered two or three times a month in autumn and once or twice a month in winter. Because of the fleshy root system, it is afraid of stagnant water and is not resistant to dryness. Water once out of the house in spring, then once every other day; once in the morning and evening in summer, foliar water should be sprayed if it is too dry; once every 3 days in autumn; buckle water in winter, as long as the basin soil is slightly moist; pour the stagnant water in time after rain.

7, temperature: not cold-resistant, except South China, all other areas should enter the room for maintenance in winter, the lowest room temperature should be kept above 5 ℃, and the time to leave the room should be from Qingming to Grain Rain.
